PRESS FOR FORMING THICK FLUID SUBSTANCES.

Specification of Letters Patent.

Patented May 21, 1907.

- Application filed January 13, 1905. Serial No. M0380.

To all whom it may concern:

Be it known that we, CHRISTIAN FREDE- RIox MUELLER, Jr, and SAMUELMUELLER, citizens of the United States, residing at Jersey City, in thecounty of Hudson, State of New Jersey, have invented certain new usefulImprovements in Presses for Forming Thick Fluid Substances, of whichinvention the following is a specification.

Our invention relates to a-machine which can be operated through themedium of hydraulic pressure, or other suitable pressure, such as steam,hydraulic pressure being preferred, for the purpose of forming andshaping substances which, while they are in said machine, constitute athick or pasty fluid, and which after the removal from the machine, formmarketable products, such for instance as macaroni or spaghetti.

Our invention is directed not only to a desirable means or method forforming and shaping said articles, but it also comprehends and includessuch means as Wlll tend to cheapen the manufacture of said product, andat the same time produces a more umform and satisfactory and marketablemerchandise.

Our invention is also directed to a compactness and stability ofconstruction, whereby not only the proper pressure can be maintained andhandled with due efficiency, but also the resultant output of themachine will be comparatively large considering the size of the machine;our machine will also lend itself to quick and satisfactory handling.

In carrying our said invention into eifect, we have produced a machinewhereby, and in which, a plurality of rows of the finished product, inleaving the compressor, w1ll so assemble themselves automatically as tofall in side by side and thereupon become a single and compact row; andthis feature we have by our arrangement hereinafter described,quadrupled, so that the compactness here1nbefore rehearsed will bearrived at, not only by the agency of the plurality of rowsautomatically assembling themselves in a single row, but by aquadrupling of thesame process, produce practically four machlnes inone, and thereby arrive at a point where the finished. article can beproduced with much greater economy than by any means, or process nowknown, or employed.

L, For thebetter understanding of our invention we will proceed todescribe it in connection with the accompanying drawings which form apart of this specification.

In these drawings Figure 1, represents a view of our improved. machine,partly in elevation and partly in vertical section. Fig. 2, is ahorizontal section on the line 22, Fig. 1, looking from the upper partof the machine down. Fig. 3, is a vertical section on a larger scale onthe line 33, Fig. 2. Fig. 4, is a horizontal section of the machine onthe line 44, Fig. 3. Figs. 5 and 6 are detail views, showing a portionof the die and the core. Fig. 7, is a detail longitudinal sectionthrough a portion of the die plate; in this view the product is shownissuing from the die plate. Fig. 8, is a crosssection of the same parts.Fig. 9, is a plan view section i looking up into the machine frombeneath.

In these drawings 1 represents girders or other suitable means forsupporting the press. 2 represents a table mounted on the said girdersor upon other suitable supports.

The table 2 is provided with two cross partitions 33 and a longitudinalpartition 4: which sub-divides the central space in said table 2 intosix receiving chambers or hoppers 5. These latter are again sub-dividedby the sloping partitions 6 as shown in Fig. 8 of the drawings.

Each of the six chambers 5 are provided with perforate tops or covers 7which form and constitute the mold or die plate or plates. Theseperforations are shown at 8. In Figs. 5 and 6 of the drawings the plates7 are shown. to an enlarged scale and here is indicated the exactconstruction of the perforations or tubes 8 which form and constitutethe dies for shaping the plastic mass which passes therethrough. v

The upper portions of the tubes or dies 8 are sloping, flaring upwardlyas shown. This construction permits and compels the proper introductionof the fluid mass into the tubes. We also provide the cores or formers 9suitably attached to, and supported on, the die plate and extending downinto the tubes 8. The resultant product, that is, the articles producedon the machine are hollow; such as macaroni.

Above the die plates 7 is the chamber 10 into which the plastic materialis introduced in bulk for the purpose of forming into the shapedarticlesaforesaid. This plastic material or thick fluid substance, such asdough, is shown in Fig. 8 of the drawings partly in the chamber 10,partly in the forming dies and partly as formed and shaped articles 12resting on the sloping partition 6. In Fig. 7, which represents alongitudinal vertical section of the same parts, the formed articles 12are shown as assuming positions side by side in a compact and unbrokenrow. This uniformity and regularity of delivery and assembling areimportant and valuable features of our invention. These said featuresare directed toward economy of manufacture and operation by reason ofcompactness of construction. T 0 further illustrate this phaseof ourinvention we will here refer to Fig. 4 of the drawings. In this figureare shown six sets of forming dies properly and sufficiently separatedeach from the other and in each set are arranged six different rows oftubes or formers. Taking the forming plate in cross section as shown inFig. 8 it will be seen that twelve deliveries of the finished articleare visible, which twelve finished articles are divided into four setswith three articles in each set. Now by referring to Fig. 4 again, itwill be seen that the perforations which constitute the forming tubesaforesaid are diagonally arranged one behind the other and that bytaking three of these perforations or tubes the space occupied therebywill be approximately, when added together, the entire space of theplate within the limits of said three perforations or forming tubes andconsequently the spaces of all these perforations, or forming tubes,adding them together from one side as far and including the third row,will be approximately the same as the entire length of the die plate; inother words the product which issues from any three rows upon the sideof a die plate will while lying side by side in a single row occupy aspace equal to the entire length of the said die plate. This is broughtout in Fig. 7 of the drawings where the die plate extends from the point13 to the point 14. The formed articles 12 are shown here in a compactrow lying side by side and extending the entire length or distance andcovering the entire space between the points 13 and 14 aforesaid. Itwill thus be seen that the product as it issues from the press as shownin cross section in Fig. 8 automatically assumes and forms itself intothe compact and continuous row shown in Fig. 7. As there are foursub-divisions as shown in Fig. 8, so there will also be four compactrows issuing from the machine as shown in Fig. 7. By this operation andarrangement we secure the economy of space before referred to and ameans also whereby the formed articles can be satisfactorily handledeither automatically by introduction into another machine for subsequentmanipulation or by hand or otherwise as may be desired. To

more particularly and again describe this phase of our invention we willrefer to Fig. 4 of the drawings. This figure shows as before stated sixcompartments or dies, each having six rows of perforations or formingtubes. To more properly emphasize and describe the points involvedherein, we will designate these rows separately as follows: The firstrow we will designate as 8'A; the second row as 8B; the third row as8*C; the members constituting these three rows lie, as will be seen,diagonally one behind the other and the combined space occupied by theperforations 8 A, 8B, and 8C, is equal to the entire space of the dieplate beginning with the near edge of the perforations 8A and endingwith the far edge of the perforations 8C; and it will be seen thereforethat the issue or product of these three perforations as shown in 8A,8B, and 8C at the right hand of Fig. 8, will lie close to each other andwithout any intervening space between them. The entire space of the lineof finished articles shown in Fig. 7 consists of a repetition of theseries 8A, 8B, and 8C. So also the product of the three rows 8D, 8E, and8F automatically arrange themselves as shown in the second compartmentfrom the right in Fig. 8. The rows 8-G, 8H, and I, arrange themselves inthe third compartment from the right in Fig. 8, and the product of rows8-.J, 8K,and 8L arrange themselves as shown in the compartment at theleft hand side of Fig. 8. The product of each of these four compartmentsof Fig. 8 produces four compact rows like the rowshown in Fig. 7. InFig. 9 we show an under side view of this machine and here the four rowsare seen fully developed and illustrated.

At 15 we show a plunger entering the com- I pressor chamber and adaptedand arranged to move downwardly in said chamber and thrust the plasticmaterial through the perforations and forming dies aforesaid.- Thisplunger exactly fits the said chamber and drives the entire productthrough the dies aforesaid.

At 16 we show the hydraulic chamber into which the plunger extends inits upward movement and at 17 we show an entrance into said chamber forthe introduction of the compressing liquid. These parts may be made inany suitable and customary manner.

At 18 we show bolts extending the length of the machine for holding theparts securely together. For withdrawing the plunger 15 out of thechamber and restoring it to its operative position as shown in Fig. 1 weprovide any suitable means such as the cross heads 19 connected by ashaft 20 to the vertical pillars 21. These parts can be operated byhydraulic means, not shown, or by any other suitable means.

The unimportant details of our invention can be varied at pleasurewithout departing from the spirit of our invention, which issubstantially the production of a machine for forming and molding thickfluid substances, such as macaroni and spaghetti whereby in theirwithdrawal from the machine they assume automatically a plurality ofcompact rows of finished product, and whereby also, the economy in theconstruction of the machine as well as in its operation is demonstratedand maintained. These results may be arrived at by mechanicalequivalents of the device such as we have shown and described, but wehave here produced a preferred and satisfactory form of mechanism whicheffectually demonstrates the utility of our invention. In carrying ourinvention into effect also, the diagonal arrangement of perforations orforming dies upon the die plate can be increased and the length of thedie plate can be extended without departing from the spirit of ourinvention so long as it substantially brings about the result which wehave demonstrated herein to be new and useful and which we shallhereinafter claim. Similarly the parts can be decreased.

Having thus described our invention the following is what we claim asnew therein and desire to secure by Letters Patent 1. In a machine forforming and shaping thick fluid substances, a die plate havingdiagonally arranged perforations and means arranged below the die platefor receiving the product therefrom and directing it into a straightline.

2. In a machine of the class described, a die plate having perforationsarranged diagonally as shown in combination with sloping partitions toreceive the product and direct it into a straight line.

3. In a machine forforming and shaping thick fluid substances, a dieplate having perforations arranged diagonally across its face, asuitable compressor as shown, and means for receiving the product fromthe die plate and directing 'it into one or more compact straight rows.

4. In a machine for forming thick fluid substances, a die plate mountedin the machine substantially as shown and described, the perforations ofthe die plate being arranged diagonally in respect thereto and meansupon one side of the machine for directing the product into a compactand perfectly straight row moving out and away from the machine in thedirection of that side and similar means upon the other side as and forthe purposes set forth.

5. In a machine for forming thick fluid substances, a die plate havingdouble sets of diagonally arranged perforations, each double set adaptedto produce two single straight and compact rows of finished product.

6. In a machine for'making macaroni or spaghetti, consisting of a dieplate having diagonally arranged perforations and means upon each sideof the machine for producing two single straight rows of the finishedproduct.
